<p>A rechargeable battery anode active material precursor producing device using a sealed reactor according to a preferred embodiment of the present invention comprises: a reactor for producing a precursor by reacting a mixed metal salt solution with a chelating agent and a basic aqueous solution; and a stirrer for stirring the reaction liquid contained in the reactor; and the stirrer does not pass through the reactor. When using the rechargeable battery anode active material precursor producing device using a sealed reactor according to the preferred embodiment of the present invention, there is no risk of the oxygen concentration becoming raised or extraneous material becoming mixed in even with a mixing flow, due to the stirrer which does not need to pass through the reactor. Also, it is possible to provide a rechargeable battery anode active material precursor producing device using a sealed reactor, wherein metal substances are not oxidised and the precursor determining characteristics are improved.</p> |
